Continuous Glucose Monitoring (CGM)
Understand glucose trends in real time, recognize patterns, and make more confident day-to-day decisions with your healthcare team.
What is a CGM?
A CGM is a tiny, friendly sensor that sits on your skin, like a small sticker. It's a little helper that checks your sugar levels all day and all night, even while you're sleeping or playing. It sends the numbers to a phone or a small reader, so you don't need to poke your finger every single time.
Why is it useful?
Old ways of checking sugar were like taking one photo every few hours. A CGM is like a video camera instead — it shows the whole story of what your sugar is doing all day, so you and your grown-ups can spot patterns and make good choices together with your doctor.
How a CGM works
It checks sugar under the skin
It doesn't check your blood directly. It checks the sugar in the fluid just under your skin, every few minutes.
It sends numbers to a device
The numbers travel to a phone app or a small reader, so you can see your sugar trend like a line going up or down.
You and your care team look together
You, your parents, and your doctor look at the pattern together to make smart, confident decisions.
Think of a CGM like a friendly weather station on your arm. Instead of guessing if it will rain, it keeps giving little updates all day, so you always know what's happening and what might come next.

About the cost
CGMs can start from around ₹3,000, but prices can be different depending on where you live and where you buy them.
It's worth checking with your own city's diabetes community or local patient groups — many families find CGMs for less through local networks, camps, or bulk community deals compared to buying alone.
Prices change often and vary a lot by brand, city, and vendor. Please confirm current pricing directly with the seller or your local diabetes community before buying.
